WebThis standardization process is called as ‘continuum removal’ or ‘convex-hull’ transformation. It allows comparison of spectra that are recorded by different sensors under different lighting conditions. The technique of making a continuum or hull is similar to fitting a rubber band over the spectrum ( Fig. 14.11 ).

WebA nice consequence of implementing 3D convex hull is that we get Delaunay triangulation for free. We can simply map each point ( x, y) into a 3D point ( x, y, x 2 + y 2). Then the downward-facing triangles of the 3D convex hull are precisely the Delaunay triangles. The proof is left as an exercise to the reader.
